Probably not. It is sounding like there could possibly be different colored "Fast Passes" you (Temporarily) get from the Grizzly River Run categorizing you into which section you are going to be placed in to watch the show. I hope someone has some more updated information, cause as far as I know right now, Disney hasnt really figured anything out yet.
Al Lutz on Miceage works for Disney and gives us the insider scoop as it comes out. Here is the latest on what he said...
*Burbank's legal and corporate red tape couldn't get the proposed "Showpass" moniker approved in time, so they'll just be calling it World of Color Fastpass when it launches next month. Get to the Grizzly River Run ticket machines early, and just hope you pull a ticket in either Yellow A, B, C, or Red A and B sections. If you pull a Blue section ticket over by the Golden Zephyr, you might as well toss 'em and wait to get into Yellow or Red at the later non-Fastpass shows*
